What is the purpose of a connecting rod?

The con-rod connects the piston to the crankshaft to transfer combustion pressure to the crankpin. There are bearing portions at both ends, the piston side is called the small end, and the crankshaft side, the big end.

Where are connecting rods?

The connecting rod is mounted on the crank pin of the crankshaft with a plain bearing. The connecting rod bearing cap is bolted to the big end. In most cases the connecting rod is hollow or provided with an internal cast oil duct to supply the gudgeon pin with lubricant.

Which is the type of connecting rod?

Bolt and Nut, Shank, Wrist pin, Piston, and Bearing cap. What are the types of connecting rod? Fork and blade rod, Master and slave rod, Billet conrods, Cast rods, Forged rods and Powered metal conrods.

How much does it cost to replace a connecting rod?

On average, expect to spend between $2,000-$3,000 for both parts and labor. Usually, the job consists of replacing the seals, gaskets, connecting rod bearings, cylinder head bolts, and flushing out the engine and cooler lines. What is this?

How do I know if my connecting rod is bad?

Signs of a Bad Connecting Rod

1. Knocking Noise From Engine. Listen for a knocking noise when the engine is running.
2. Low Oil Pressure. Check the oil pressure.
3. Excessive Oil Consumption. Determine if the engine is using excessive oil.
4. Visual Inspection.

Do connecting rods wear out?

Fatigue is the main cause of broken connecting rods–especially in older engines. The constant compression during the power stroke and stretching during the exhaust stroke, over thousands of times a minute, eventually wears the metal out and it becomes brittle and finally breaks.

How long do titanium connecting rods last?

Titanium Connecting Rods That comes with a price; titanium rods typically are typically four times the cost of a billet steel rod. The other drawback is that titanium rods do have a fatigue life in race applications and are typically switched out every 40-80 hours.

Can I replace just one connecting rod?

Occasionally, it may be necessary to replace one of these parts during the operational life of the engine. Connecting rods with the same identifying letter are installed when the engine is new; if only one or two rods are to be replaced in the field, they must be those marked with the letter S.
